Definitions
- the present invention relates generally to the field of replacing portions of the human structural anatomy with medical implants, and more particularly relates to an expandable implant and method for replacing skeletal structures such as one or more vertebrae or long bones.
- FIG. 1 illustrates four vertebrae, V 1 -V 4 of a typical lumbar spine and three spinal discs, D 1 -D 3 .
- V 3 is a damaged vertebra and all or a part of V 3 could be removed to help stabilize the spine. If removed along with spinal discs D 2 and D 3 , an implant may be placed between vertebrae V 2 and V 4 . Most commonly, the implant inserted between the vertebrae is designed to facilitate fusion between remaining vertebrae. Sometimes the implant is designed to replace the function of the excised vertebra and discs. All or part of more than one vertebrae may be damaged and require removal and replacement in some circumstances.
- Implants are known in the art for use in a corpectomy procedure.
- One class of implants is sized to directly replace the vertebra or vertebrae that are being replaced.
- Another class of implants is inserted into the body in a collapsed state and then expanded once properly positioned.
- Expandable implants may be advantageous because they allow for a smaller incision when properly positioning an implant. Additionally, expandable implants may assist with restoring proper loading to the anatomy and achieving more secure fixation of the implant.
- Implants that include insertion and expansion mechanisms that are narrowly configured may also provide clinical advantages. In some circumstances, it is desirable to have vertebral endplate contacting surfaces that effectively spread loading across the vertebral endplates. Effective implants should also include a mechanism for maintaining the desired positions, and in some situations, being capable of collapsing. Fusion implants with an opening may also be advantageous because they allow for vascularization and bone growth through all or a portion of the implant.
- Expandable implants may also be useful in replacing long bones or portions of appendages such as the legs and arms, or a rib or other bone that is generally longer than it is wide. Examples include, but are not limited to, a femur, tibia, fibula, humerus, radius, ulna, phalanges, clavicle, and any of the ribs.
- One embodiment of the invention is an expandable medical implant for supporting skeletal structures including a body and a sprocket disposed within the body having gears configured to receive a turning mechanism to rotate the sprocket, the sprocket including a first end with a threaded portion and a second end with a threaded portion.
- the embodiment may also include a first end component sized to engage with the threaded portion of the sprocket first end and a second end component sized to engage with the threaded portion of the sprocket second end.
- a further embodiment of the invention is an expandable medical implant for supporting skeletal structures including a body and an expansion means disposed within the body for converting rotational movement substantially transverse to the longitudinal axis into linear expansion of the implant along the axis.
- the embodiment may also include a first end component sized to engage with the expansion means and be moved away from the body by operation of the expansion means and a second end component sized to engage with the expansion means and be moved away from the body by operation of the expansion means.
- the expansion means is captured within the body for protection of tissue adjacent to the skeletal structures.
- Another embodiment of the invention is a method of placing an expandable medical implant within a spinal column.
- the method embodiment may include making an incision adjacent to a vertebral body and removing at least a portion of the vertebral body.
- the expandable medical implant with a body, an expansion means disposed within the body for converting rotational movement into linear expansion of the implant, a first end component sized to engage with the expansion means and be moved away from the body by operation of the expansion means, and a second end component sized to engage with the expansion means and be moved away from the body by operation of the expansion means; and a surgical instrument comprising a cannula and an inner shaft disposed at least in part within the cannula, the inner shaft configured to couple with the expansion means.
- the method may also include releasably attaching the cannula to the body, inserting the expandable medical implant at least in part into a volume left open after removal of the portion of the vertebral body, rotating the inner shaft to activate the expansion means, detaching the cannula from the body, and removing the surgical instrument through the incision.

- this can be particularly important with respect to significant neural structures such as the spinal cord, dura, exiting nerve roots and adjacent lateral nerves.
- significant vascular structures extend along the spine including the aorta and vena cava which respond poorly to engagement with abrasive structures due to the pulsatile nature of blood circulation.
- the unitary outer structure of housing 110 provides a continuous curved surface from atraumatic engagement with surrounding tissue.
- a lock screw 128 may be advanced into engagement with upper sprocket 210 and in particular with one of the grooves 218 to prevent further rotation of the sprocket. Additionally, although not required, a further locking screw 129 may be advanced into engagement with lower sprocket assembly 270 and one of the grooves 272 . It will be appreciated that locking the relative rotation will insure that the height established during the surgical procedure will be maintained throughout the life of the device. While a pair of locking set screws has been shown for the purposes of illustration, it will be appreciated that other mechanisms and techniques may be utilized to inhibit the relative rotation and encourage maintenance of the established height.
